HENRY B. RIEDER, OF APPLE CREEK, OHIO.

VISE.

SPECIFICATION forming part of Letters Patent No. 395,079, dated December 25, 1888.

Application filed August 22, 1887. Serial No. 247,625. (Model.)

To all whom t may concern:

Be it known that I, HENRY B. BIEDER, a citizen of the United States, residing at Apple Creek, in the county of lVayne and State of Ohio, have invented certain new and useful Improvements in Vises, of which the following` is a specification.A

My invention relates to improvements in vises; and it consists in certain novel features, hereinafter described and claimed.

In the accompanying drawings, Figure l is a side elevation of a vise provided with my improvements. Fig. 2 is a vertical section of the same taken just in rear of the lever and looking in the direction indicated by the arrow. Figs. 3 and et are similar views showing the handle adjusted to rotate the screw in opposite directions, and Fig. 5 is a cross-section on line a: of Fig. 2.

Referring to the drawings by letter, A designates a bench-vise provided with a clamping-screw, AE, to secure it to the bench, and having the screw C journaled in its Iigid jaw, all of the usual construction. On the outer end of the screw (l, l mount a tulcruin-plate, D, and between this plate and the fixed jaw of the vise l rigidly secure the screw and a ratchet-wheel, E, having a series of radial notches, G, in its periphery, as shown most clearly in the sectional views.

H designates a lever, which is pivoted tothe outer end ot' the fulcrum-plate and extends beyond the same to form a handle, L. The inner portion of the lever passes between and under the L.shaped clips or lugs J, formed integral with the opposite edges of the fulcrum-plate, and the inner extremity ol' the lever is shaped to provide the spurs or prongs l, which are adapted to engage the notches in the wheels E.

The construction ol' my device being thus made known, its operation and advantages will be readily understood. Then the vise is in use and properly adjusted to clamp the work, the handle hangs below the same outof the workmans way, as clearly shown in Figs. l and 2. It it be desired to release the work from the vise, the outer extremity or handle of the lever l is pushed to one side, as shown in Fig. 3, causing the prong on the inner end of the lever to engage the ratchet-wheel, and the pressure being continued, the lever will be carried around in the direction indicated by the arrow, carrying the ratchet wheel around with it, and thus rotating the screw to move the sliding jaw away from the rigid jaw. Then it is desired to clamp the work, the lever is moved to the opposite side, as shown in Fig. l, and as will readily be understood.

It will be observed that by my device the power is exerted directly on the ratchet-wheel and the screw, and that the fulcrum-plate serves merely as a support tor the lever. The lugs or clips on the fulcrum-plate serve to hold the lever to said plate, and thereby prevent its swinging away from the ratchetwheel, and also serve to limits its play, so that when thrown into engagement with the ratchet-wheel it will not become accident-ally disengaged therefrom. My device is thus rendered easy and certain in its operation, and its simplicity and efficiency are obvious.

Then the vise has been properly adjusted, the lever is disengaged from the ratchet-wheel and at once falls to its normal position below the ratchet-wheel.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

As an improvement in vises, the combination of the screw, the ratchet-wheel rigidly secured thereon and having radial notches in its periphery, the fulcruni-plate mounted on the screw and provided with the integral L- shaped lugs on its opposite side edges, and the lever pivoted to the outer end ot' the fulcruIn-plate and extendingbeyond the saine to form a handle, the said lever also passing under the Lshaped lugs and having its inner extremity shaped to form spurs or points adapted to engage the notches in the ratchetwheel, substantially as described.
